A firstrecessed portion corresponding to the extending portion is formed on anouter ring of the third opening. The extending portion engages with thefirst recessed portion to enable the circumferential positioning of thesealing plug 1131 and the fastening member 1132.

Referring to FIGS. 5, 7, and 9, the atomizer base 14 engages with theatomizer cover 114, and the atomizer assembly 15 is located between theatomizer base 14 and the atomizer cover 114. The atomizer assembly 15includes a cylindrical heating coil 151 made of ceramics. An inner holeof the heating coil 151 communicates with the air flowing pipe 112. Athrough hole 141 communicating with the inner hole of the heating coil151 is defined in a middle portion of the atomizer base 14, such thatair flow can flow into the inner hole of the heating coil 151.

In some embodiments, two silicone covers 152 are arranged on outer ringsof the two opposite ends of the heating coil 151 respectively, such thata middle portion of the heating coil 151 forms a liquid absorbingportion 1511 which absorbs the liquid solution flowing out through theliquid outlet 1141. The heating coil 151 is heated after conducted tothe battery device to atomize the liquid solution. The smoke flowstowards the suction nozzle 121 through the air flowing pipe 112.

The silicone covers 152 perform a sealing function between thecorresponding end of the heating coil 152 and the atomizer cover 114/theatomizer base 14, preventing the leakage of the liquid solution throughthe inner hole of the heating coil 152. In addition, the arrangedposition of the silicone cover 152 can be adjusted to control the amountof the liquid solution flowing into the heating coil 152, which preventstoo much liquid solution from flowing into the heating coil 152. Thus,leakage of the liquid solution caused by incomplete atomization of theliquid solution can be avoided.

In some embodiments, the cartridge 111, the air flowing pipe 112, andthe atomizer cover 114 are made of ceramics. Thus, before the liquidsolution injected into the electronic cigarette gets heated by theheating coil 151, the liquid solution only contacts the components ofthe electronic cigarette which are made of ceramics and silicone ratherthan metal or plastic. Thus, the situation that harmful ingredients frommetal or plastic affect the user's health can be avoided.

Referring to FIGS. 5, 7, and 10, the air inlet assembly 16 is arrangedon one end of the atomizer device 10 opposite to the sealing unit 113.The air inlet assembly 16 communicates with the air flowing pipe 112.The air inlet assembly 16 includes an air inlet tube 161 and a secondadjusting ring 162 rotatably arranged on an outer ring of the air inlettube 161. The air inlet tube 161 engages with the atomizer base 14, suchthat the air inlet tube 161 can communicate with the through hole 141 ofthe atomizer base 14. In other embodiments, the air inlet tube 161 candirectly communicate with the inner hole of the heating coil 151.

In some embodiments, an air inlet hole unit 163 is formed in acircumference of the air inlet tube 161, allowing air to flow into theair inlet tube 161. The air inlet tube 161 engages with the atomizerbase 14, such that the air flowing into the air inlet tube 161 can flowinto the inner hole of the heating coil 151.

A second adjusting opening 1621 is defined in the second adjusting ring162, corresponding to the air inlet hole unit 163. The rotation of thesecond adjusting ring 162 adjusts an area of a portion of the air inlethole unit 163 which allowing air to flow into the air inlet tube 161,thus, the amount of air flowing into the electronic cigarette and theamount of the smoke sucked by a user of the electronic cigarette can beadjusted.

Referring to FIG. 10, in some embodiments, the air inlet unit 163includes a plurality of second air inlets 1631 arranged on thecircumference of the air inlet tube 161. The air inlets 1631 are ofdifferent areas. An area of the second adjusting opening 1621 is no lessthan that of the largest second air inlet 1631. The rotation of thesecond adjusting ring 162 enables the second adjusting opening 1621 tocommunicate with different second air inlets 1631 of different areasrespectively, thus, air can flow into the air inlet tube 161 through thecorresponding second air inlet 1631 to enable the adjusting of theamount of air flowing into the electronic cigarette.

Referring to FIG. 11, in other embodiments, the air inlet unit 163 caninclude a number of third air inlets 1632 arranged on the circumferenceof the air inlet tube 161. A second recessed portion 1622 is formed onan inner wall of the second adjusting ring 162, and the second recessedportion 1622 extends to an end surface of the second adjusting ring 162.Two boundaries of the second recessed portion 1622 in thecircumferential direction of the second adjusting ring 162 respectivelycorrespond to two end boundaries of the third air inlets 1632 in thecircumferential direction of the air inlet tube 161. The secondadjusting valve 162 can be rotated to adjust an area of a portion of thethird air inlets 1632 communicating with the second recessed portion1622. For example, the second adjusting ring 162 can be rotated todifferent positions such that air can flow into the atomizer devicethrough the corresponding third air inlet 1632 communicating with thesecond recessed portion 1622, thus, the amount of air flowing into theair inlet tube 161 can be adjusted.

Referring to FIGS. 10 and 11, in order to ensure the accuracy of therotating position of the second adjusting valve 162 and ensure thepositioning of the second adjusting valve 162 after the second adjustingvalve 162 is rotated, an elastic column 164 is arranged on the outerwall of the air inlet tube 161, and a number of clamping mechanisms 1623engageable with the elastic column 164 are formed in an inner ring ofthe second adjusting ring 162 along a circumference of the secondadjusting valve 162. The elastic column 164 engages with thecorresponding clamping mechanism 1623, thereby enabling the positioningof the second adjusting ring 162.

Referring to FIGS. 12 and 13, in other embodiments, the suction nozzle121 can be clamped to the adjusting valve 13, and the adjusting valve 13can be driven to rotate between the first position and the secondposition by the suction nozzle 121. For example, the adjusting valve 13may include the adjusting cover 131 and the sealing cover 1131 locatedbetween the adjusting cover 131 and the sealing unit 113; a firstprotrusion is arranged on the sealing cover 1131, and a secondpositioning hole is defined in the adjusting cover 131, corresponding tothe first protrusion; and the first protrusion engages with the secondpositioning hole to enable the circumferential positioning of thesealing cover 1131 and the adjusting cover 131.

The rotation of the suction nozzle 121 drives the adjusting cover 131and the sealing cover 1131 to simultaneously rotate between the firstposition and the second position. The first opening 1131 penetrates theadjusting cover 131 and the sealing cover 1131 and corresponds to theliquid injection channel 1131 of the sealing unit 113. When theadjusting valve 13 is in the first position, the first opening 1311communicates with the liquid injection channel 1131, thus, the liquidinjection channel 1131 is opened; when the adjusting valve 13 is in thesecond position, the first opening 1311 misaligns with the liquidinjection channel 1131, thus, the liquid injection channel 1131 isclosed.

In some embodiments, a second protrusion is arranged on the suctionnozzle 121 and a clamping slot is correspondingly defined in theadjusting cover, and the second protrusion can be clamped into theclamping slot to enable the circumferential positioning of the suctionnozzle 121 and the adjusting cover 131. The suction nozzle 121 iscapable of moving back and forth along an axial direction to be clampedinto the adjusting cover 131 or to disengage from the adjusting cover131. When liquid injection is required, the suction nozzle 121 is pushedinwards to engage with the adjusting cover 131 and thus drives theadjusting valve 13 to rotate to the first position to open the liquidinjection channel 1131. After the liquid injection is finished, thesuction nozzle 121 is rotated to drive the adjusting valve 13 to rotateto the second position, and then the suction nozzle 121 is slid outwardsto disengage from the adjusting cover 131. An elastic member 124 isarranged between the suction nozzle 121 and the adjusting cover 131. Theelastic member 124 is configured to provide an elasticity to keep thesuction nozzle 121 from disengaging from the adjusting cover 131, thus,mis-opening of the liquid injection channel 1131 caused by mis-rotationof the adjusting cover 131/the suction nozzle 121 can be avoided.
